Econergy's qualified electricians deliver the full range of commercial electrical installation services, from power distribution systems and three-phase installations to distribution board upgrades, commercial lighting, machinery supplies, and full or partial rewires.

If you’re planning an electrical installation for a commercial or industrial site, you already know it’s not a job you can leave to chance. The stakes are higher, the systems are more complex, and the compliance requirements are stricter than anything you’d deal with on a domestic project.
What you need is a team that’s done this before, in environments like yours, with the same kind of pressures and timescales you’re working to.
That’s where we come in. Econergy works with businesses, site managers, main contractors, and landlords across the UK on electrical installation projects of all shapes and sizes. Whether you’re fitting out a new premises, replacing ageing infrastructure, or getting the power supply ready for new machinery, we’ll handle it properly, on time, to standard, and without the drama.
Commercial and industrial electrical installation is about designing, supplying, and installing the electrical systems that power your building and everything in it. It’s a different world from domestic electrical work; the systems are bigger, the loads are heavier, the compliance requirements are tighter, and the consequences of getting something wrong are a lot more serious.
At this level, electrical installation can mean anything from wiring a new office fit-out to putting in a full power distribution system for a large manufacturing site. What stays the same across all of it is the need for the work to meet BS 7671 (IET Wiring Regulations) and be signed off with the right certification.
That’s what we deliver, every single time.

It’s tempting to go with the cheapest quote, or to keep patching an ageing system rather than dealing with it properly. In a domestic setting, that might be a minor inconvenience. In a commercial or industrial environment, it can be a much bigger problem.
Poorly installed or non-compliant electrical systems can lead to:
When we carry out your electrical installation, you get a system that’s been designed properly, installed to standard, and backed by full documentation. That’s what protects your business and your people.

On a commercial or industrial site, the electrical installation rarely happens in a vacuum. There are other trades to work around, programmes to stick to, and operations that can’t just grind to a halt while the work goes on. We get that, and we plan accordingly.
We Start By Understanding Your ProjectBefore we talk prices or timescales, we want to understand what you actually need. What are the operational requirements? What loads are you running? Are there phasing constraints we need to work around? Are there existing systems we need to integrate with? The answers shape everything, so we ask the questions upfront rather than making assumptions.
We Design Around Your RequirementsWe don’t just turn up and start installing. We think about what the finished system needs to do, how it needs to perform, and how it fits with everything else on site. That means you end up with an installation that works properly from day one, not one that needs revisiting six months later.
We Work to Your ProgrammeTime costs money on a commercial site, and we’re well aware of that. We’ll commit to a realistic programme, tell you early if anything changes, and do everything we can to avoid holding up other trades or disrupting your operations.
We Sign Off ProperlyEvery installation we complete is tested, inspected, and certified to BS 7671. You’ll get the full documentation, electrical installation certificates, test results, and anything else you need, so you have a proper record of the work for your files, your insurer, and any future inspection.
There’s no shortage of electrical contractors out there, so it’s a fair question. Here’s what we think makes the difference:
We’ve spent years working in genuinely demanding commercial and industrial environments. This isn’t occasional commercial work on the side; it’s what we do. We understand complex sites, tight programmes, and the kind of pressure that comes with high-stakes electrical projects.
We keep communication simple and honest. You won’t get jargon-heavy reports or vague updates that leave you none the wiser. We tell you what we’re doing, why we’re doing it, and where things stand, and if something changes, you’ll hear it from us first.
We do the job properly, and we prove it. Every installation is completed to BS 7671 standards and backed by full certification. We don’t cut corners, and we don’t consider a job finished until the work is right and the paperwork is in order.
We think about the bigger picture. Because Econergy also specialises in solar PV, battery storage, and EV charging, we can think about how your electrical infrastructure fits into a broader energy strategy. Not many electrical contractors can offer that kind of joined-up thinking.
And we’re based in Cambridgeshire but work right across the UK, so wherever your site is, we can be there.
